Chang, Meng-Yang,Lee, Nien-Chia

, p. 867 - 872 (2012)

A variety of 1-indanonyl oxepanes with the novel structure of indanonyl oxepanes was prepared from reaction of hydroxybenzaldehydes via a series of reasonable transformations, including the regioselective PhBClmediated allylation (or Claisen rearrangement), one-pot reaction of ring-closing metathesis and the Wittig olefination, hydrogenation, and the Friedel-Crafts intramolecular cyclization.
